CEIMENTING MACHINE.

Application filed April 22, 1920. Serial No. 375,834.

T 0 all whom it may concern:

Be it known that I, WILLIAM F. LAUTEN- SGHLAGER, a citizen of the UnitedStates, and residing at Cincinnati, in the county of Hamilton and Stateof Ohio, have invented a new and useful Improvement in CementingMachines, of which the following specification is a full disclosure.

My invention relates to cement-applying machines, primarily applying acoating of cement along the margin of material. The material at itsmargin is drawn across a revolving cement-applying brush.

In machines of this class, the revolving cement brush receives a supplyof cement continuously from a revolving cell-faced or corrugated cementdistributing roll, mounted at the end of a supply passage or feedinghead, connecting with a cement pot or reservoir. The distributing rolland brush rotate in a clockwise direction, thus moving at their point ofcontact in a direction counter or opposite to each other. It has beenthe general practice to mount the distributing roll below the feedinghead or passage connecting with the cement pot or reservoir and engagedinto a cylindrical recess in the base of the head, as a sleeve orcylinder valve, so that the head on one side of the roll provided afeeding spout contacting with the periphery of the roll for preventingthe feeding of excess cement to the periphery of the roll or an amountgreater than would be carried by the cells in the face of the roll. Thehead of the opposite or return side of the roll is arranged to provide amouth to receive any excess cement carried upon the periphery of theroll and lead the same back into the feeding head. The excess cement onthe return side of the roll instead of being drawn or carried back intothe cement feeding head after a few roll revolutions accumulated uponthe periphery of the roll between the incoming end of the feeding headand brush in such proportion as would materially interfere with the useof the machine.

The commercial field for the machine is largely in shoe factories forapplying cement containing volatile ingredients, which, when exposed tothe atmosphere evaporates readily, allowing the cement to congeal orcoagulate when allowed to accumulate upon the periphery of thedistributing roll, especially when having a thick grade of cement.

The light or thin grades in volume do not: and thus drop withholds anyreturn of the surplus cement carried upon the roll into the head. Thecement will ooze and permeate through the return opening in the-head andadd to the increasing accumulation on the return side of the roll. Suchaccumulation is further augmented by the relative opposite directions ofthe distributing roll and brush rotation at their point of contact, anddifferential rate of speed, the roll rotating at a lower rate functions.as a wiper for the brush instead of a distribution.

It is therefore, an object of the invention to arrange the partsrelatively to overcome the above stated objections, and provide amachine which may be run continuously with the cement distributing roll,delivering a well regulated uniform supply of cement to the brush, inwhich no roll wiper or clean ing is required while the machine is beingcontinually operated.

Another object of the invention is to arrange the cement supplying headat one side of the rotary" cement distributing roll which coacts withthe mouth of the head to bring the outlet point or line of the feedinghead in close proximity to the point of contact of the cement applyingbrush with the distributing roll.

Another object of the invention is to utilize a rotary liquid cementdistributing roll as a valve for closing a cement sup'portport oropening, the valve being of a cylindrical dimension to bear against asemi-cylindrical seat surface extending above the opening-to bring theheight of the end of the joint between the contacting valve and seatsurfaces to an'elevation which will prevent seepage or permeation ofcement upwardly there-- through.

The cement usually used in the manufacture is of a character having arubber foundation or base, known to the trade as rubher cement, andvarious grades, kinds and 1 drawings colors are used for differentclasses and character of material. Under the prevailing practice aseparate machine is required for each grade of cement, otherwise thereservoir of the machine has to be drained and the parts thoroughlycleansed in chang ing from one grade or kind of cement to another.lVith' my improved machine the change can be readily and convenientlymade by substituting one cement distribut ing unit for another, with theroll, supply head,and pot or reservoir as a distributing unit detachablefrom the machine, which feature provides a further object of theinvention, and in providing the machine with a plurality of distributingunits one for each of the different grades or kinds of cement required.

With the foregoing, and other objects in view, which more fully appearin the following description of the accompanying drawings, forming apart of this specification, like characters of reference in the denotecorresponding parts throughout the several views, of which Figure 1, isa side elevation of my improved cement machines which maybe mounted uponan standable table or bench.

Figure 3, is a detail top plan view of the cement distributing roll andits valve controlled cement supply passage within the end of which theroll is journaled.

Figure 4, is a vertical section on line 1-4L Figure 2.

Figure 5, 1s a section taken on line 5-5 Figure 4, illustrating themeans employed for detachably connecting the distributing roll with itsdriving shaft.

Many of the detail parts of the machine in construction comparesimilarly, and are standard with like parts of cement applying machinesshown in prior patents issued to me April 24, 1917, No. 1,228302, andNo. 1,223,403, and the machine herein shown and described is alsoapplicable for practicing the method of cementing the margins offlexible material disclosed in a prior patent. issued to me April 24,1917, No. 1,223,404, so that no further elaboration as to the use andpurposes of the machine for the various kinds of work particularlycontemplated need be included herein. Reference to the aforesaid patentsbeing had for such purposes.

The frame of the machine in its preferred form comprises a column 1,extending upwardly from the base, which is arranged to be secured to'asuitable support or table. The column 1, has an overhanging arm 2, and adownwardly extending bearing extension 3, for supporting thetransmission elements and cement applying instrumentalities sutlicientlyfree from the column so that the operator has full and convenient accessto the cement applying brush, and the work can be freely passed or wipedacross the brush for applying a coating of cement.

The rotary cement applying brush l, is of circular form with itsbristles radiating from the axis of a specially built-ug type found mostetficient for cementing the margins of flexible material used in themanu: facture. of shoes. The brush is divided into annular rowsseparated by rings or disks,

loosely mounted upon the hub 5 of the brush.

The. hub is provided with an angular flange at one end of the brush andguard plate 6, of particular shape, at the opposite end of the brush.This guard plate is loosely mounted upon the, hub of the brush and willbe more fully described in detail hereafter. The

plate is the duplicate of the cement control-.

ling device orplate shown and described in the above-named priorpatents. The hub of the brush is removably keyed or pinned upon the endof the main driving shaft 7, journaled in bearings in the column 1,.and

bearing extensions 3. The shaftis provided I with a pin 8, engagedthrough the shaft and into open end notches9, milled, into the end ofthe hub. This adapts the hub to be readily slipped on and off of theshaft when the screw 10, threaded into the end of the shaft has beenremoved. The shaft 7, is driven by r a pulley 11, fixed on the end ofthe shaft. A second shaft 12, journaled in bearings in the column 1, andbearing extension 3, extends to provide a cellular surface, as cementconveying pockets 17, for conveying the cement from a cement passage orchamber to the brush.

The cement distributing roll, as shown in section Fig. 4t, is fixed upona sleeve 18, and

the sleeve concentrically engages upon the end of the shaft 12. Thesleeve 18 has a pin 19 engaged and secured transversely through? one endengaging into a transverse slot milled into the end of the shaft forremovablv keying or connecting the roll to the shaft- Hub plates 20, 20engaged. concentrically upon sleeve 18,'at opposite sides I of thecement distributing roll, provide means for rotatively mounting the rolland its sleeve upon the. end of the cement feeding head 21. The cementfeeding or conveying head may be described as an L-pipe fitting Orconduit providing a horizontal cement passage, for conveying the cementto the periphery of the distributing roll'or as a cement supply orchamber, within which the roll revolves for taking up a supply of rollreceiving 22 projects upwardly and forwardly from the feeding end of thehead and over the roll and its lower or interior face recessed be tweenthe sides of the roll, as shown at '23, Fig. 4, to provide acement'rc'ceiving throat or mouth at an elevation above the supplychamber of the cement supply head, through which any surplus cementcarried upon the periphery of the roll may be carried therewith into thecement supply chamber. The lip presents an increased roll overlappingbearing surface on, the descending or seat bearing side of the rollperiphery according to the direction of roll rotation, so that anefficient seal against any escape of cement when the roll is stationary,eliminating objections heretofore encountered in cementing machines ofthis class. The outlet Or discharge throat between the end of the supplyand periphery of the roll is brought at a lowermost point or elevationof the supply chamber, immediately adjacent the cemcnt ap lying brush,so that any cement escaping t rough said discharge threat is depositeddirectly upon the brush and is carried forward by the brush, while thebrush is rotating. The brush is rotated in a direction from the throatand forwardly with the roll at the point of brush contact with the roll,so that there is no possible wiping or scraping action between thecooperating parts, to permit an accumulation of cement. Thisconstruction and coordinate direction of the roll and brush rotation,within a cement supplying zone of the parts, renders possible thedistribution of a continuous, regulated and uniform supply to the brush,when the parts are in operation, without the liability of surplus cementaccumulation.

The cement supply head has a threaded end for connecting the shank ornipple end 24, of the cement pot 25, and the supply from the pot to thesupply chamber of the head is controlled by a plug valve engaged intoand through the head, and thereby forms a part of the head. The pot 25,at its lower spherical face, is provided with a pro jection lug 26,adapted to rest upon an arm 27, extending laterally from the free end ofthe overhanging arm of the pedestal. The arm 27 is notched to receive apin 29 projecting from the lug for locking the pot and cement supplyhead or unit in a properly installed position upon the pedestal andrenders the same easily removable. vTo remove,

the cement supply unit of-the pot supply head and distributingIroll, itis-swung lip-- wardly about the axis of the drive shaft 12,

releasing the pin or locking engagement with the pot supporting arm,and-'when in such upward position the unit is slid endwise from the endof the shaft 12.

This enables an easy and quick substitution of one cement supply unitfor another when a change fromone grade or quality of cement to anotheris desired. In utilizinga plurality of cem'ent'supply units for thevarious kinds of cement, capable of being interchangeably installed uponthe machine, no time is consumed in making the change from one kind ofcement-to another, and the cement may be stored in the units until entirely consumed, which resultsrin quite a saving over the older methods,in whichthe supply head and pot were drained and flushed foreachchan'ge. The cement pot is provided with the-usual strainer 30 andsealing cap 31. I

In the guard plate 6'the construction 1s substantially the same as thecement controldevice shown in my prior Patent No. 1,233,403, heretoforementioned, mounted about the axis of rotation of the brush. The

plate, in the form shown, is provided With a. central or middle diskportion which contacts with the hub of the brush for preventing seepingof cement to the brush shaft and i held upon the shaft by the screw 10.In order to prevent rotation of the plate with the shaft and brush, itis provided with a tail piece 34 arranged to contact the cement applyinghead, and thus limit its rotative movement about the shaft in onedirection and permitting a movement about the shaft m an oppositedirection if such should be desired for cleaning purposes. The plate isprovided with a lateral sloping lip 35, and a second peculiarly formedlip 36 opposite from the lip 35, the purpose and function of which isfully described in the specification of the aforesaid Letters Patent.

A guide arm 37 fixed to the depending bearing extension 3 of the columnor pedestal, is provided at the opposite side of the brush from that ofthe plate 6 against which the material to be cemented is engaged forproperly guiding the work across the brush. The plate 6 as a guide, mayhowever, be variously modified or eliminated as occasion may require,the same being incidental as apart of machine and not particularlyessential to or concerned with this invention.
